Recently, the painstaking observational results support the existence of the multi-pair plasmas (MPPs)
not only in space environments (viz. cometary comae [1]}, chromosphere, upper regions of Titan's atmosphere [2]},
solar wind, D-region (\(\rm H^+, O_2^-\) ) and F-region (\(\rm H^+, H^-\) ) of the Earth's ionosphere [3]}, etc.)
but also laboratory situations (viz. Fullerene (\(\rm C^+, C^-\) ) [4]}, plasma processing
reactors [5]}, neutral beam sources [6]}, etc.). Plasma physicists are solely
practicing wave dynamics, basically, ion-acoustic (IA) waves (IAWs) in which restoring force is
provided by the electrons thermal pressure and moment of inertia is provided by the pair-ion (PI) mass density. The
adiabatic presure/dissipative force from the inertial component of the plasma system provides a great effect
to generate various nonlinear electrostatic structures (viz. shocks, solitons, and envelope solitons) in
MPPs. The existence of positive ions in MPPs drastically alters charge neutrality condition [7]},
the dispersive property [2]}, and nonlinearity of the IAWs [7]}.
